I want to be able to unlock my iPhone 4, currently on version 4.1 (shsh saved), base band 02.10.04.

I have heard (possibly misheard) that since there is currently no unlock for this basband, I shouldn't jailbreak until the unlock comes out. Is this true, or could I jailbreak and have no consequences?

If I do jailbreak, what should I use? Limerain or greenp0ison? Should I take any precautions before jailbreaking?
